About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG825675477 or 825675477. Listed at 11 retailers as of November 1, 2026, with prices from $160 to $1,460, a $1,300 spread on the same certified stone. MOH London lists it at $1,460. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
